Scalability - Hitachi AMS 2100 Hardware Manual

Scalability

Using the components available, users can construct a variety of systems
that meet a wide range of needs, as described here.
• A single AMS 2100 base unit that contains from 4 to 15 disk drives, or a
larger system using a single AMS 2100 base unit with 4-15 drives and
attached expansion units and/or high-density expansion units. The AMS
2100 supports a maximum of 159 drives.
• A single AMS 2300 base unit that contains from 4 to 15 disk drives, or a
larger system using a single AMS 2300 base unit with 4-15 drives and
attached expansion units and/or high-density expansion units. The AMS
2300 supports a maximum of 240 drives.
• When RKS/RKES connect RKAKS/RKAKX, disk drive can be
mounted up to 159 units.
• When RKM connect RKAKS, disk drive can be mounted up to 231
units.
• When RKEM connect RKAK/RKAKS/RKAKX, disk drive can be
mounted up to 255 units.
However, when mounting subsystems mixing RKAKs and RKAKSs or RKAKs/
RKAKSs and RKAKXs, a maximum of Disk Drives can not be mounted. For
more details, refer to
NOTE: The configuration other than the number of Additional Chassis
displayed in each table can be created, but the unusable slots increase in
the chassis. The slot indicates the installation place of Disk Drives in the
chassis.The number of slots in the Additional Chassis is as follows:RKAK:
15 slots, RKAKS: 24 slots and RKAKX: 24 slots each for RKAKX-A and
RAKAKX-B
